File Chunking / Partitioning

Splitting a file into smaller pieces allows for a more efficient overall upload, and powers some Fine Uploader features such as pausing, and resuming uploads. Fine Uploader can also upload multiple chunks for the same file concurrently.

Pause / Resume Uploads

Pause an in-progress upload when you know you are about to go offline, and safely resume them again right where you left off.

Delete Uploaded Files

Upload the wrong file? Use this feature to delete what you don't need.

Upload to the Cloud

Send files directly to Amazon’s Simple Storage Service (S3) or Microsoft Azure's Blob Storage service to minimize backend code and scale with the number of users. You can even optionally bypass your local server entirely with S3.

Image Previews & Scaling

Give your users an in-browser preview of images before they upload. You can even have scaled versions of images generated and uploaded automatically, keeping EXIF data intact.
